Molecular Gas Kinematics in Barred Spiral Galaxies [PDF]

The Astrophysical Journal, 1999
To quantify the effect that bar driven mass inflow can have on the evolution of a galaxy requires an understanding of the dynamics of the inflowing gas. In this paper we study the kinematics of the dense molecular gas in a set of seven barred spiral galaxies to determine which dynamical effects dominate.

Secular Evolution and the Formation of Pseudobulges in Disk Galaxies

, 2004
We review internal processes of secular evolution in galaxy disks, concentrating on the buildup of dense central features that look like classical, merger-built bulges but that were made slowly out of disk gas. We call these pseudobulges. As an existence

On the Age Distribution of Classical Cepheids in the Galaxy

Astronomische Nachrichten, Volume 346, Issue 5, June 2025.
ABSTRACT We revisit the problem of the positive correlation between age and Galactocentric distance seen in Galactic Classical Cepheids, which at first sight may seem counter‐intuitive in the context of inside‐out galaxy formation. To explain it, we use the Besançon Galaxy Model and a simulation of star particles in the Galactic disc coupled with ...

Stellar Populations in the Barred Spiral Galaxy NGC 4900 [PDF]

, 2010
We present OASIS observations obtained at the Canada-France-Hawaii Telescope for the SB(rs)c galaxy NGC 4900. About 800 spectra in the wavelength range 4700-5500 AA and 6270- 7000 AA have been collected with a spatial resolution of ~50 pc. This galaxy is

In Vitro Validation of Pulsed Electromagnetic Field (PEMF) as an Effective Countermeasure Against Inflammatory‐Mediated Intervertebral Disc Degeneration

JOR SPINE, Volume 8, Issue 2, June 2025.
ABSTRACT Background Intervertebral disc (IVD) degeneration (IDD) is the main contributor to chronic low back pain (LBP), the leading cause of disability worldwide, with a significant impact on the quality of life and health of common people. The etiology of IDD is still unclear, but it has been largely demonstrated the crucial role of inflammation and ...

Gas Dynamics in the Barred Seyfert Galaxy NGC4151 - II. High Resolution HI Study

, 1998
We present sensitive, high angular resolution (6" x 5") 21-cm observations of the neutral hydrogen in the nearby barred Seyfert galaxy, NGC4151. These HI observations, obtained using the VLA in B-configuration, are the highest resolution to date of this ...

Gas and Stellar Motions and Observational Signatures of Co-Rotating Spiral Arms [PDF]

, 2014
We have observed a snapshot of our N-body/Smoothed Particle Hydrodynamics simulation of a Milky Way-sized barred spiral galaxy in a similar way to how we can observe the Milky Way. The simulated galaxy shows a co-rotating spiral arm, i.e.

Unique starch biosynthesis pathways in wild rice revealed by multi‐omics analyses

Plant Biotechnology Journal, Volume 23, Issue 6, Page 2429-2445, June 2025.
Summary Australian wild rice species (AWS) possess unique starch properties characterized by a slow digestibility rate. However, the genomic and transcriptomic variations of starch‐synthesis‐related genes (SSRGs) influencing starch physiochemical properties in AWS remain unclear.
